Subtask 1 report: emission control system identification. Task 25

Technical Report · Fri Oct 22 00:00:00 EDT 1982

OSTI ID:5657413

The emphasis here is the identification of emission control systems through information contained in the vehicle identification number (VIN). The data base which maps each combination of carline and engine symbol into the possible engine families is described in detail. The methods used in developing this data base are summarized. The instances in which major features of the emission control system can not be determined unambiguously from the VIN are identified. Recommendations are presented for resolving the ambiguities with the assistance of auto manufacturers. The ability of the several manufacturers to assist in further decoding of VINs and is reported and the information presently available on costs of doing so is provided. Data files that will be used to extract manufacturer, carline, and engine symbols from VINs and then access the master VIN/engine family data base are listed. The master data base is listed in its entirety. The cases of ambiguous emission control identification are listed. (MHR)
